Cosmopolitan Japonais, with locations in Chicago and Las Vegas (the New York location closed in early 2011), is the place for lounging amid sleek, sexy décor and popping signature sushi rolls into one’s mouth (or the mouth of one’s date). Until recently, 2005 Chicago Rising Star Gene Kato was on hand to prepare hot appetizers and fusion entrées. And in a restaurant so geared towards flirtation, what better to cap an evening than a little something sweet? Pastry Chef Kym DeLost’s desserts fuse classic French and Japanese flavors and techniques with imaginative touches. DeLost’s take on tarte tatin employs a Toban Yaki—a traditional Japanese cooking vessel powered by steam—just the ticket to heat things up at night’s end.
